Attachment and Biobehavioral Catch-Up

Attachment and Biobehavioral Catch-Up (ABC) helps caregivers provide nurturing care and engage in positive parent-child interaction. ABC supports caregivers in reading children’s cues in order to provide a responsive, predictable environment to enhance children’s behavioral and regulatory capabilities. ABC offers three programs: Newborn, Infant, and Early Childhood.

What is the model’s approach to providing home visiting services?

Home visits take place weekly. Services are provided for 10-12 sessions. For the Newborn program, ABC requires families to enroll when the child is younger than 6 months. For the Infant program, ABC requires families to enroll when the child is between 6 and 24 months old. For the Early Childhood program, ABC requires families to enroll when the child is between 24 and 48 months old.

ABC’s service population includes the following:

Families with low incomes
Families with a history of child abuse or neglect/involvement with child welfare system
Families who consider their child to be growing up in a challenging environment
Children experiencing a caregiving transition (e.g., foster care placement, adoption)
